I'm the other way. I _know_ I miss out of a lot of things I'd know about and be interested in attending if I had a FB account still. And I'm still happy with my choice not to be there. There are groups I've lost touch with, because they no longer bother running a website or mailing list, and do everything through FB these days. Even groups I'd have bet money on _not_ going that way (looking at you, DorkBot Sydney...)
